Help, regarding Flipkart Axis cc

So I have Amazon icici credit card 90K limit, and 2 other older fd cards, Recently I got a Pre-approved message on my Flipkart app regarding the Flipkart Axis Bank credit card.

But when I am applying for it, it is asking if I am salaried or self employed, but I am not any of them, so how can I apply? Can I just say I am self employed and fill out the form ? Or should I leave it?
